This invent-ion relates to recnfrn'cing or 3 against accidental removal,and an object'of I of the lower margin of the spacer sheet and theinvention is to provide a device. or. this character which be securelyattached to a sheet in a ready and corvenient inannerand which is simpleto to manufacture. l Further objects will hereinafter app-ear and theinvention is shown in one of its preferred forms in theaccompanyingdrawings in which U :f m r Fig.1 is a cross section of afiling cabinet drawer showing a spacerv sheet in elevation provided witha reenforcing'device;

The illustrated embodiment of the invention comprisesa drawer of afiling cabinet having end walls (not shown) side walls 1 and 2, an opentop 4, and a bottom 3 which is formed with a slot 5 extendinglongitudinally thereof. Arranged inside the drawer is a suitable numberof spacer sheets 6 of relatively stiff material such as cardboard,bristol board or ot 161 suitable material which separate groups ofpapers or records from each other to keep the papers in'position thus tofacilitate finding of a certain paper. To identify the various groupstabs 7 may be fastened in anysuitable manner to the upper portion of thespacer sheets and arranged to project above the margin of the sheets.These tabs may have. suitable indicia according to F i the subjectmatter of each particular group.

order to hold the spacer sheets in posi tion and prevent them from beingaccidently pulled'out of the drawer when papers adjacent thereto areremoved. eachspacer sheet is provided with a tab 8 integral with thelower margin thereof which is arranged to extend into the slot 5 in thebottom ofthe drawer. Formed in the tab or extension 8 is a perforation 9elongate longitudinally of the sheet which is arranged to receive thennnnroncrne DEVICE non sinns or rs'aronArrous.

usual locking rod 10 extending the length of the drawer and detachablyconnected to the opposite ends thereof. It will thus be understood thatthe rod 10 must beremoved before the spacer sheets 6 can be withdrawnfrom the drawer. i

It frequently happens that when papers or other contents of the drawerare withdrawn the spacer sheets 6 are accidently grasped and if a suddenpull is exerted thereon the perforations 9' are torn out so thatthereafter the sheets cannot be held in position and 7 their usefulnessfor the purpose intended is greatlyimpalredi- In order to obviate thisobjection a reenforcing device A may enclose thelower margin of the tabor extension 8 and surround the perforation 9v in such a manner thatoutward pull on the spacer sheet 6 will not operatetto tear the rod 10out of the sheet because the device not only protects the edges ormargin of the card immediately over the opposite side of the device.

surrounding and forming the perforation but also reenforces aconsiderable part of the sheet in the vicinity of the perforation.

Preferably the reenforcing device A is constructed from a flexible, thinplate 11 of brass or other'suitable material out out to providesubstantially a U-shaped notch 12 and a substantially Y-shaped notch 13is formed in the sheet metal piece in opposed relation to the notch 12.In applying the device to the spacer sheet 6, the metal piece is foldedapproximately along the line 14; over the lower margin of the tab orextension 8 in such a manner that the notch 12 partially surrounds theperforation 9, as indicated. To hold the device A securely in positionflaps 15 which are formed by the Y-shaped notch are folded approximatelyalong the dotted lines shown in Fig. 4 through the perforation 9 and Theedge of the card which forms the perforation is thus firmly grippedbetween the two metal pieces, when the flaps 15 are passed through theperforation and folded down on the opposite side. Preferably three flaps15 are provided on the reenforcing device arranged on three sides of theperforation 9 so that the 8 in the vicinity of the perforation 9creasing 0i? HEWV'YOBK, N. .Y.,.

or folding which would weaken the connec tion between the sheet andlocking rod 10 is prevented. A further advantage of the deviceresides inthe fact that there are no sharp projecting edges which would prevent anumber of sheets from being arranged closely Although I have shown anddescribed a construction which at this time is the best form known tome, it is to be understood that numerous changes in details ofconstrnction, arrangement and selection of materials may be etl ectedwithout departing from the spirit of the invention especially as definedin the appended claims.

I claim a 1. The combination with a sheet or card having a perforationadjacent a margin thereof, of a pair ct elements on opposite sides atthe sheet in the region of said perforation, and integral parts on oneelement for engaging the other, passing through the per fora: tion andreenliorcing' the sheet surrounding the perQora-tion and adjacent themargin.

2. The combination with a sheet having a perforation adjacent a marginthereof, of a member enclosing the adjacent margin of the sheet andhaving extensions on opposite sides of the sheet in the vicinity of thepertoration, and an element integral with one of eeaeee said extensionsengaging the ot ier extension through the pertora ion and firmlygripping the sheet therebetweeln thereby to protect the sheet fromtearin in the direeti on of the m argin.

3. The combination of a spacer sheet having a marginal extension at oneend thereof,

said marginal extension having a perforat t-ion to l'GCGlVG a rod forlocking the spacer sheet in position, and means for reent'orcing saidperforation comprising asheet metal plate enclosing the margin of saidextension and constructed partially to surround said perforation, andtabs on a portion of said plate arranged to extend through said per-'loration and fold over another portion of the plate thereby detachablyto fasten the plate to the sheet. 1 V

a. A device of the class described comprising a plate *onstructed to befolded over a mar in oi" a sheet having cat-out portions and designed topartially surround a perfoia tion in said sheet when folded, andtoldable tabs integral with a portion of the plate arranged to extendthrough the perforation and engage another )ortion ot' the plate therebyto reenforce the sides of the perforation.
